I don't understand why this is happening? I scooped out all the mould off of the soil one month ago, only to have it come back even thicker than it was before! I tried letting the soil dry out for weeks, and that didn't help either. I am not sure what to do. I don't want to have to throw out my Jade plant (his name is Patrick), but it can't be good to have a houseplant that has mouldy soil. Any ideas as to what I could use to rectify this problem? I would prefer to not have to spend money on some kind of fertilizer, if at all possible.
